Optimal Control of Matrix Converters [PDF]
2019 21st European Conference on Power Electronics and Applications (EPE '19 ECCE Europe), 2019 In this paper a new control technique for matrix converter based on a Linear Quadratic Regulator (LQR) is proposed. Stabilization of matrix converter is often challenging due to the input filter resonance. The proposed method is compared with classical approaches for matrix converter control.
